PIPE BAND.

Application filed October 22, 1925. Serial No. 64,120.

This invention relates toimprovements in pipe bands such as are used toplace about leaky pipes to stop the leaks.

The principal object of my invention is to provide a device for thepurpose which is very easily applied and which has clamping boltsmounted in such a manner that a straight and even'pull may be applied tothe ends of the band to draw the same together, which results in evenhand all around the same.

A further object is to connect the bolts to the band in such a mannerthat the ends of the band may be separated the neccessary distarnze toenable said band to be placed around the pipe, without removing the nutsfrom the bolts and without takingout the bolts themselves.

The bands are used in connection with suitable water-tight packing orsealing means, and another object of my invention is to construct theband in such a manner that when cinched around a pipe, the sealing meanswill be firmly engaged with the pipe so that not only is leaking pastsaid means positively prevented but any likelihood of the sealing meansblowing out is eliminated.

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly etl'ective for the purposefor which it is designed.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a. perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views:

Fig. 1 is a side View of a one-piece band showing my improved clampingarrangement.

Fig. 2 is a cross section on the line 2-2 of Fig. 1, showing the band asapplied to a pipe in connection with the sealing or packing means.

Fig. 3 is a top plan view of the device.

Fig. i is a side view of a modified or two piece type of band,particularly intended for large size pipes.

Fig. 5 is an end view of one of the band sections of the type ofstructure shown in Fig. 4:.

Referring now more particularly to the characters of reference on thedrawings, and

pressure on the particularly at present to F igs. l and 3, the numeral 1denotes the band slit transversely, and. with the ends adapted tooverlap as shown in Fig. 1. The edges of the band are turned overinwardly all around to form rentinuous heads 2.

Projecting outwardly from the band adacent one end is a bearing lug 3,whose outer portion 4: is circular in cross section and with its axisparallel to that of the band. The portion at forms the bearing for aremovable pin 5. Projecting outwardly from the band adacent the oppositeend thereof is a transv :sc bolt supporting lug (5, provided wit-htransversely spaced and vertical slots 7 on its facenearest the lug 3.The lug is preferably made of a single piece of sheet metal, bent to besubstantially V-shaped, and with lts outer face a substantially in aplane at right angles to a line projected through the center of pin 5and slots 7. Between the lugs bolts 8 extend. These bolts have eyes 9 onone end to receive the pin 5, the eyes fitting in notches 10 cut in thetop of the lug 3 to a sufficient depth to enablethe bolts to be loweredso that the pin will engage the eyes. Nuts 11 on the opposite ends ofthe bolts then bear against thetace a of the lug 6, there being orificesb in the face a through which the belts project, such orifices being ofa lesser diameter than the eyes 9 to prevent the bolts dropping oil ofthe clamp when the pin 5 is removedfroni such eyes 9.

It will therefore be seen that when the nuts are tightened up a straightand even pull is applied to the band adjacent its ends, so that saidband will be cinched evenly and firmly about a pipe 12 to which the bandmay be applied. Also the bolts being straight throughout, no bendingstrain is placed thereon.

The slots 7 are completely closed around their edges; Thus when theclamp is assembled the bolts 8 are first set through the slots 7 andorifices b and the nuts 11 mounted on the bolts. Thereafter the nuts andbolts cannot be lost oft of the clamps as neither the nuts 11 or eyes 9can pass through the orifices bl.

The operation of placing and assembling the band around the pipe iscarried out as follows The split band is opened and fitted around thepipe and strips of rubber or like packall) ing material l i are placedabout the pipe in line with and project slightly to each side of thebends 2 so that as the band is einched up the packing strips will hecompressed by the beads intermediate their edges and leave the innerportions of substantially normal thickness. This will prevent anytendency oi? the packing strips to blow outi zirdly under pressure andhence will prevent leek- :ltfc poet the bend Anothm: strip of rubber orlike packing material 15 placed between the m'erlep iing portions of thesplit band as the some are drowntogether, thus n'mhine n leek-proofjoint at this pointalso.

Vi'hen the bend and pat-hing; strips the all in position on the pipe theeyes i) are moved into :ilineinent with the bearing 4;. The pin 5 isthen passed through the hearing -il and eyes 1) and locked in positionby cotter pins The niits 11 are then advanced on the bolts 8 to draw theends of the split band together to fix the clamp on the pipe as tightlyin; desired.

The ehnnps are designed 1n-inmrily for use on lnre'e pipe ci'innectedwith water systems of various kinds where it is essential that noaccidental loosening of the chnnp will he pos sible while at the sometime a quick eiuerll'fillt't i' release of the clamp sometimes required.These two conditions a re cared for in my structure by having the boltand nut enclosed within one lug and eecured to but quieldy releasablefrom the other through the medium of the pin 5 and cotter pins 5.

In the modified. form of structure shown in l igs. at end 5, the band isformed of two sections 16, each having :1 pair of lugs 3 and (icorresponding to the lugs 53 and 6 on the first described type, toreceive the oppositely disposed clumping bolts 8.

lllheselinnd sections are provided with continuous circular and concavegrooves 17 adjacent their outer edges, forming: seats for not form adeparture 'lroni the spirit ot the invention, as defined by the eppendedcliinis.
